The recovery shouldn't have anything to do with the "Trust Zone." You can try, but it will still probably fail. Before you try to downgrade, and after you flash the ICS recovery, boot into the AP FastBoot screen and see what the date says there. If it's from Nov, you'll probably still get a failed root attempt.

Download TWRP image on your phone from: titanroms.com/upload/rec.img

Please get to an adb prompt and run these commands:

su
cd /sdcard
dd if=/dev/block/platform/msm_sdcc.1/by-name/recovery of=/sdcard/recbak1.img
dd if=/dev/block/platform/msm_sdcc.1/by-name/recovery of=/sdcard/recbak2.img

Please ensure that both copies are 10MB. The dd command should end by saying "10485760 Bytes Copied" on all of the "dd" commands.

Now, you should have two backups of the recovery partition and the TWRP Image you downloaded from here all on your sdcard.

You can follow with these commands AFTER your backup has completed.

cp /sdcard/Download/rec.img /sdcard/rec.img
dd if=/sdcard/rec.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery
dd if=/dev/block/platform/msm_sdcc.1/by-name/recovery of=twrprecbak.img
mount -o remount,rw /system
mv /system/etc/install-recovery.sh /system/etc/install-recovery.bak
mv /system/recovery-from-boot.p /system/recovery-from-boot.bak
reboot recovery


In the event of a failed attempt at this you can run the following from adb:

su
cd /sdcard/
dd if=/sdcard/recbak1.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery

Give me a holler if you don't understand this well. Good luck, guys.

C:\>cd sdcard
The system cannot find the path specified
is the any other way? I did not had time till today to try it out... Maybe to find the recovery manually some way thru the adb interface?

You aren't at an adb prompt.

you must have your device plugged in and type "adb shell" when it says "C:\>" in order to communicate with the device.


It works great for me; however, I am unsure as to whether it will work with a locked BL.
